I just noticed in trade-a-plane

Since ECI was bought out by continental and Superior filed bankruptcy and seems to be back in a limited fashion, cylinder prices are not posted like they used to be. There used to be a half dozen ads listing cylinders for both Lyc and Cont replacements with prices and now zip, not a single ad. I got a feeling that cylinders will become to get expensive in the near future....Tim
